NAME

Test::Ping - Testing pings using Net::Ping

VERSION

version 0.203

SYNOPSIS

This module helps test pings using Net::Ping

use Test::More tests => 2;
use Test::Ping;

my $good_host = '127.0.0.1';
my $bad_host  = '1.1.1.1;

ping_ok(     $good_host, "able to ping $good_host" );
ping_not_ok( $bad_host,  "can't ping $bad_host"    );
...

DESCRIPTION

Using this module you do not have to work with an object, but can instead use actual procedural testing functions, which is cleaner and more straight forward for testing purposes. This module keeps track of the object for you, starting and closing it and provides a nifty way of testing for pings.

SUBROUTINES/METHODS

ping_ok( $host, $test )

Checks if a host replies to ping correctly.

This returns the return value and duration, just like Net::Ping's ping() method.

ping_not_ok( $host, $test )

Does the exact opposite of ping_ok().

create_ping_object_ok( @args, $test )

This tries to create a ping object and reports a fail or success. The args that should be sent are whatever args used with Net::Ping.

create_ping_object_not_ok( @args, $test )

Tried to create a ping object and attempts to fail. The exactly opposite of the create_ping_object_not_ok()

EXPORT

ping_ok

ping_not_ok

create_ping_object_ok

create_ping_object_not_ok

SUPPORTED VARIABLES

Variables in Test::Ping are tied scalars. Some variables change the values in the object hash while others run methods. This follows the behavior of Net::Ping. Below you will find each support variable and what it changes.

BIND

Runs the bind method.

PROTO

Changes the proto hash value.

TIMEOUT

Changes the timeout hash value.

PORT

Changes the port_num hash value.

HIRES

Changes the package variable $hires. By default, it is enabled.

SOURCE_VERIFY

Changes the package variable $source_verify.

SERVICE_CHECK

Changes the econnrefused hash value.

INTERNAL METHODS

_has_var_ok( $var_name, $var_value, $description )

Gets a variable name to test, what to test against and the name of the test. Runs an actual test using Test::Builder.

This is used to debug the actual module, if you wanna make sure it works.

use Test::More tests => 1;
use Test::Ping;

# Test::Ping calls the protocol variable 'PROTO',
# but Net::Ping calls it internally (in the hash) 'proto'
# (this is documented above under PROTO)
# this is checking against Net::Ping specifically

$Test::Ping::PROTO = 'icmp';
Test::Ping::_has_var_ok(
    'proto',
    'icmp',
    'Net::Ping has correct protocol variable',
);

_ping_object

When debugging behavior, fetching an internal object from a procedural module can be a bit difficult (especially when it has base inheritance with another one).

This method allows you (or me) to fetch the actual Net::Ping object from Test::Ping. It eases testing and assurance.

This is used by the Tie functions to set the variables for the object for you.

use Test::Ping;
use Data::Dumper;

print 'Object internals: ' . Dumper( Test::Ping->_ping_object() );

Or you could also change the Net::Ping object to one of your own:

use Test::Ping;
use Net::Ping;

Test::Ping->_ping_object( Net::Ping->new(@opts) );

And doing it with tests:

use Test::More tests => 2;
use Test::Ping;

create_ping_object_ok( 'tcp', 2, 'Creating our own Net::Ping object' );
ping_ok( $target, "Yay! We can reach $target" );

However, you should be warned. I test for a Net::Ping object so trying to pass other objects will fail. If anyone needs this changed or any reason, contact me and I'll consider it.

DEPENDENCIES

This module uses Net::Ping, Tie::Scalar and Carp.

Test::Timer is used in the test suite.
